That depends on your car. You should check the manual. If it's not explicitly mentioned, you should check in the manual which fuse belongs to the accessory supply and then check the rating of that fuse in the fuse box.

The amperage of a 12-volt accessory supply can vary depending on the specific device or accessory being used. However, it is common for 12-volt accessory supplies to have amp ratings between 5 to 30 amps. It is important to check the specifications of the supply and the device you are connecting to ensure compatibility and safe operation.
To calculate the amps, divide the power in watts by the voltage. If the voltage is 120V, then 320 watts would be approximately 2.67 amps.
A 100 amp service will supply your electrical current needs UP TO 100 amps.When doing load calculations on a 100 amp panel it can only be loaded up to 80 amps.
A 18000 watt generator supplying power at 240 volts would supply 75 amps (18000 watts ÷ 240 volts = 75 amps).
To answer this you have to know how many volts will be used. If you know the voltage then you can calculate the current by dividing voltage into wattage. For example; an electric heater rated at 700 watts when plugged into a 115 v outlet will draw 700/115 = 6.08 amps of current.
To find the amperage, you need to know the voltage of the circuit. The formula is: Amps = Watts / Volts. If we assume a standard voltage of 120V (for US), then 87 watts at 120 volts would be approximately 0.725 amps.
